GitHub Copilot vulnerability allows arbitrary code execution on Windows

By PulseAugur Editorial · [1 sources] ·

A critical vulnerability, CVE-2026-103572, has been identified in GitHub Copilot within Visual Studio and SQL Server Management Studio. This flaw allows for arbitrary command execution by exploiting how Windows handles filenames with trailing dots. An attacker can inject malicious commands into a configuration file, which Windows then normalizes, bypassing Copilot's edit gate and enabling the execution of unauthorized code. Microsoft has released a patch for this vulnerability. AI

IMPACT This vulnerability highlights the need for robust security validation in AI-powered coding assistants, especially concerning OS-level path handling.

RANK_REASON The item details a specific vulnerability and patch for a software tool, not a frontier model release or significant industry-wide event.
